Natural Circulation Condensing Boiler

Natural Circulation Condensing Boiler

The world since the 1970s, pressure hot water natural circulation condensing boiler, especially in the northern region will get extensive application in China. Its popular not only because of low cost, easy to manufacture, more simple management, operation and safety features in its. Because of pressure hot water boiler has been widely used in various industries, it is especially important to use precautions, especially for new people to take over, should note the following:

Select heating natural circulation condensing boilers what are the considerations for the heating system, we propose the functional principle of the boiler and a lot of doubt, this simple to explain: household independent heating system, the first essential is a stable heat source, that is, heating boilers for the family is a simple heating boilers, for it is a city or a region, we need a lot of heating boiler heating stations were running protection of the public. 1. The inner two energy saving boiler combustion process, combustion of a fuel itself, and the other is to produce the fuel gas flammable mixture in a sealed high-temperature gasification and combustion processes. Boiler reasonable structure, the fuel gasification process stability, integrity, and the use of anti gasification burner, arranged dedicated economizer. Up to 85% thermal efficiency of the boiler, energy-saving effect. 2. The water temperature and water flow constant water temperature, no, no, no change, is a measure of the boiler is the main quality standards. Old residential water heaters commonly large amount of water or less, high or low temperature. According to a company's HVAC engineer, boiler now only one instead of the old heat exchanger, gas and water flow ratio control is not an exact match. But today's new boiler using a secondary heat exchanger. By completely secondary heat exchanger, complete remission contradiction gas two-phase flow of water, the water temperature is fairly constant, the flow does not change. 3. easy to control a good control system is an effective guarantee the normal operation of the combustion safety, testing, maintenance, daily operation and failure analysis are all important. Therefore, the choice of high-performance boiler is particularly important, especially for the elderly and children in the home. By-room temperature control not only the freedom to set their own needs heating temperature, can also be pre-set temperature before returning home, so that they will be able to enjoy the warmth of a home. 4. Look for boiler service procurement business, buying boiler products, especially large tonnage, is perfect after-sales service is an extremely important factor. In fact, due to the imperfections of production and after-sales service network, many boiler brands in the market is difficult to guarantee. Business and professional services to improve network and service system, not only the performance of enterprises and planning, more attention is to look at business and professional ability, each link is a professional, to ensure efficient and smooth transition of the whole process.

How to ensure the safe operation of the natural circulation condensing boiler? Boiler is a high-temperature, high-pressure thermal equipment, is one of the special equipment, according to the State Council, "Regulations on Safety Supervision of Special Equipment", using the boiler should pay attention to the following safety precautions: 1, it should be accompanied by "technical safety specifications of the design documents boiler factory , product quality certification, safety and the use and maintenance instructions, supervision and inspection certificate (safety supervision and inspection certificate performance). " 2, boiler installation, maintenance, alteration. Engaged in the installation of the boiler, maintenance, renovation of the unit shall obtain special equipment installation and maintenance certificates issued by the Provincial Quality and Technical Supervision, before engaging in the boiler installation, maintenance, alteration. Construction unit before construction will be prepared for installation, maintenance, alteration in writing inform the special equipment safety supervision and management department of the municipality or district, and will start informing sent to the local county level Quality and Technical Supervision for the record, told immediately after construction. 3, inspection of boiler installation, maintenance, transformation. After construction, the construction unit To State Quality and Technical Supervision of Special Equipment Inspection and hydrostatic testing of the boiler installation supervisory inspection declaration. After passing by the State Quality and Technical Supervision, State Special Equipment Inspection, County of Quality and Technical Supervision involved in overall acceptance. 4, registration boiler. After the boiler inspection, the use of units required under "special equipment registration and use of management rules", fill "boiler (census) Registration Form", the State Quality and Technical Supervision to register and obtain a "registration certificate to use special equipment safety . " 5, operation of the boiler. Boiler operation shall be trained and qualified to obtain "special equipment operator certificate" certified personnel to operate, use must be strictly abide by the rules and eight systems, six record. 6, check the boiler. Periodic inspection of boiler once a year, not be used without safety periodic inspection of boilers. Safety accessories safety valve of the boiler regular inspection once a year, pressure gauge biannually verified, may not be used without the periodic inspection of the safety accessories. 7, non-pressure boilers will be installed for the boiler pressure. Do not use water level gauge, safety valve, pressure gauge three safety accessories insufficiency boiler.

Luoyang, Henan Province issued the "Luoyang coal consumption reductions embodiment (2019-2020 years)", the program proposes: To continue to promote alternative coal consumption reduction, the implementation of industry "electricity instead of coal" project.

2016-2018 years, the city of Luoyang excess capacity, coal-fired boiler demolition, energy saving, clean energy alternative through a series of measures to resolve the power industry, pushing the total coal consumption control achieved some success, but the energy mix partial coal, thermal power installed capacity of migraine and thermal power multi siege pattern has not fundamentally changed, there is still emphasis on the industrial structure, high energy-consuming industries continued to increase the proportion of energy consumption, coal consumption is highly concentrated and other issues. Especially since 2018, comprehensive energy consumption of coke, chemical high energy-consuming industries rise significantly, the whole society electricity demand continues to grow, the amount of coal for power generation system tune up utility power plants rise, not fall, some counties (cities, districts) large-scale industrial coal consumption rise, not fall. Therefore, Luoyang City will continue to work to phase out coal-fired boilers to improve the quality of atmospheric environment.

"Plan" put forward the overall goal of coal governance: By 2020, the city's total coal consumption and strive to 2015, down from about 23% control in less than 20.3 million tons. Among them, the total consumption of non-coal power industry control in less than 9.6 million tons, the total coal consumption in coal-fired units ganged public control in less than 10.7 million tons.

"Plan" requirement, the industry needs all kinds of hot water, steam, hot air in the production process, and gradually promote regenerative and direct thermal electric industrial boiler applications. In the metal processing, casting, ceramics, refractories, glass and other industries to promote electric furnaces, industrial kilns and encourage qualified to carry coal to electricity.

Vigorously promote clean heating pilot city construction, 2019, 2020, respectively, the implementation of urban and rural residents electricity instead of coal, 110,000. 2019, 2020, respectively, to complete the electrical heating 500,000 square meters, 800,000 square meters.

In addition, the "plan" also proposed to accelerate the development of clean energy and new energy, the implementation of comprehensive improvement of coal-fired facilities, the city will no longer approve the domain, and the new 35 tons of steam coal-fired boilers, accelerate the elimination of 35 tons of steam / h and coal-fired boiler.
